IMPROVEMENT IN' MACHINERY FOR MAKING FLUTED ROLLERS.

Specification forming part of Letters Patent No. 50,997, dated November 14, 1865.

To all whom it may ctr/warn Be it known that I, WILLIAM WEILI), of the city of Manchester, in the county of Lancaster and Kingdom of Great Britain, have invented certain Improvements in the Manufacture of Fluted ltollers used in machinery for preparing, spinning, and doubling cotton, wool flax, silk, and other fibrous materials; and I do hereby declare that the-following is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.

I may first premise that the invention hereinafter described is part of an invention for which Letters Patent for Great Britain were granted to me under the title of-iniprovement in fluted rollers vused in' machines for preparing, spinning, and don bling cotton, wool, flax, silk, andv other fibrous materials and in the manufacture of such rollers, and dated the 20th September, in the year of our Lord 1859, and that Letters Patent have aleady been granted to me in the United States for the improvements in fluted rollers, and also for one method of manufacturing such improved rollers and other fluted rollers, and the improvements hereinafter described relate to another method of In akin g my improved diagonal fluted rollers included under-my British patent; andinclination from one of each boss to the other,

so that they are inclined and the drawings of the improved machinery to be hereinafter described show two methods, one by whichflutes of irregular pitch or inclination may be cut, and the other by which flutes of either regular or irregular pitch or inclination may be cut.

' Figure l is a side elevation, parts in section and Fig. 2, an end view of an ordinary planing-machine adapted for the manufactureof my improved fluted rollers with reversed diagonal or inclined flutes'by the ordinary cutting or planing process.

The bed of the machine is marked (1, its feet a, and the upright side framing (d, the cross slideway b, the slide a, the tool-holding slide (Z, the tableof the machine J. The drivingpulleys are marked f, and are. placed on the first and slow-motion shaft f, which drives, by a pinion, f a wheel, f on a shaft, f, a wheel, f, on the boss of one of the driving. pulleys f, on the shaft f, drivesa pinion, f on the quick-motion shaft f upon-which is a pinion which also gears with the wheel f on the shaft f. The shaft f carries a pinion,

f which gears with thetoothed rack g on the under side of the table 9.

The parts above referred to are the ordinary and well-known parts of a planing-machine.

The roller 2 is mounted on the table g of the. machine as when cutting 'straightflutes, and

the manner of rotating the roller to cut another flute is also partly the same so far as using a ratchet-wheel and click for rotating the roller.

h is a head-stocksecured to the table 9. It carries a spindle or axis, h, upon which two ratchet-wheels h are secured, and between the ratchets being set so that there will be nomore play when the lever h is moved than is necessary to enable one click it to. be lifted from its ratchet-wheel. The spindle h has a square end, which fits the square hole in the end of I the roller, 2, which is supported at intervals by brackets Jr, secured to the table g.

The lever ]L3 is jointed with a rod, '5, which is also jointed to another lever, 2", on a shaft, '5

which is carried by two bearings, (ti, secured to the bed a of the machine. The shaft i has a groove from end to end into which a key fits, which is secured in the boss of the lever 41, which is slidalong the shaft i by the movement imparted to the table 9, the boss of the- I level; i being slid to and fro on the shaft i by a bracket, gt, secured to the table g, which bracket g fits on .each side of the boss of the lever V.

On the end of the shaft i a lever, '5 is keyed, which is jointed to-one end of a rod, t the other end being jointed on a crank-pin, j, which is adjustable so as to get a longer or shorter radius in a groove formed in a disk-plate, j, secured on the end-of a shaft, 7c, rotating in bearings a attached to the bed a of the machine. The shaft 70 is geared by bevel-wheels k with the intermediate shaft, 0, which, by a wheel, 6 and pinion e, gears with the shaft f giving motion to the table g. The wheel e -and pin-1 ion a are not shown in the model, not being essential to show my invention.

The wheels gearing the two shafts and 0 should be so proportioned that while the table gtravels overa space equal to the length of a a rotation, and the crank-disk j. should be set so that when the conn'ectingro'd i arrives at what are commonly termed the 5, dead-points or centers the point of the cutting-tool will be at tbe'same time midway on the blank space between the bosses on the roller.

.It will be seen. that with the arrangement of mechanism described the shaft 2' will be made to oscillate, and that its oscillations will be conveyed to the roller 2.

The .cuttingrtool l is similar to that usually employed for cutting straight flutes, being a thin piece of steel secured by a bolt in a slit formed in a holder, Z. This holder 1 is circular, and is placed in bearings in the tool-holding slide 0, sor'that it can be freely rotated or oscillated on its axis, the point of the cuttingtool'l being placed in a line correspondin g with the axis on which the tool-holder l oscillates- The object of this arrangement'istohring the cutting-tool in the line of thecut; v

The upper end of the tool-holder lvhas an arm, Z fixed upon it, which is jointed to one end of-a rod, 1, the other end being jointed with one end of a lever, Z having its fulcrum on astud, Z sec'ufed'to the framing. Thelower' end of this lever Z has an anti-friction bowl upon it, which enters the groove of a doubleand to this mechanism the ordinary mechanism is connected, which is employed-for selfacting the vertical movements of the cuttingtool I, butinstead of the lever being loose on" the screw 0 and acting by a click or a ratchetwheel fasten thelsaid screw, the lever is fast to the screw 0 so that the reversing-gear imparts oscillating movements to it. Consequently the tool .will be raised at one end and lowered at the other end of the movement of the table, this being arranged so that thevtool will be down during the cutting-stroke of the table, but up so as to pass clear of the roller during the back-stroke. The roller is turned so as to cut the next flute by means of an inclined piece, m, fixedon the tool-holding slide 0, which acts upon a tail-piece from one of the clicksh working in the ratchet-wheels W, and lifts it clear of the teeth at the end of the cutting movement of the table g. To explain the operation of this incline piecem more clearly, it may be assumed that the table 9 has just arrived at the end of its cut, the point of the cutting tool I being halfof the length of the blank space between bosses past the last boss on the roller, and that the lever h has atthe same time arrived at one of its extreme movements to the right, looking at Fig. 2. In this case the'ratchet-click 7&4 on the right will be the pushing-click and thatto the left will be free and can be lifted. Now, the inclinem is set so as to have lifted the ratchet-click h on the left clear of the teethbefore the lever 7L3 has completed its oscillation to the right-say by the space ofa tooth and a quarter of the ratchet-consequently, when the back oscillation of the lever h and back movement of the tableg commences the ratchet k and roller 2 willhave no motion. The click on the right will lift and pass over a tooth in its ratchet and drop, and the click on the leftwill have passed over a tooth of its ratchet, being held up bythe incline m, but before it can over another tooth it willhave escaped from the incline m, and thus both clicks will again have held of their ratchet-wheels, the roller having been rotated to the extent of one tooth by the operation, whichwill be repeated at the end of every cut. The incline of the flute produced by the crank-pin j will not be uniform in pitch, but. that part of it which comes upon the boss willbe a sufficiently near approxima- "tion, and by the use of a crank-pin (made adjust-able) the increase'o'r decrease of the inclination is readily obtained but if a uniform inclination is required itwill be obtained by substituting a suitably-shaped cam in place of the disk and crank-pin, the cam acting on a bowlcarried by alever having itsfulcrum on a stud fixed in the framing, to which lever the end of the connecting-rod i must be jointed.

The arrangements described. will be found sufficient-for a large class of fluted rollers namely, those having bosses and spaces of uniformleng th-butthere is another arrangement of mechanism which I employfor fluting-rollers with either regular-or'irregular bosses-or spaces, which will beillustrated by Fig.3, a partial end view, and Fig. 4:, a partial plan view. In substituting this mechanism the shafts k and e are dispensed with and a lever, p, is employed. The axis'of its fulcrum, being a stud, 19, secured to the bed a, is placed in a vertical position One end of the "lever p is jointed to the rodt' The other end of the i lever (the fulcrum being between its two ends) carries an anti-friction'bowl which works in a box-cam path, 12 secured to the edge or under side and lengthwise of the table g. This cam-path is equal to the length of the roller to be operated upon, and is shaped with inclines of the length and pitch required by the bosses and spaces on the roller and the inclination of the required flutes. The lower-end of the lever Z is connected with the said leverp, actuated by the cam-path p on the, side of the table g, so that the inclination of the cuttingtool Z is changed in accordance with the change in the inclination of the flute.

When rollers are to'be operated upon. hav-- ing only one boss of considerable length, then it may be necessary to give a considerable. amountot' oscillating movement to the roller, in which case the lever h clicks h, and ratchet-wheels 7L2 must he placed. on a shaft in another headstock, (buton the table g,) the shaft plied. The shaft 70 will only have in' this case to make half a rotation for the length of the one boss and proportionate space at each end.

It will be readily understood that several rollers may be placed end to end (the table of the machine being long enough) and that there may he s'everalhead-stocks hand cutting-tool slides, according to the width of the machine, all actuated from the same sources by merely adding connectingmechanism,which can readily be accomplished by a' mechanic conversant with this class of machines.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

So constructing and arranging the machine vices herein described, and for the purpose'described.

W. WEILD.
